SIXERS CO-OWNER Marc Leder, at whose Florida home Mitt Romney remarked that 47 percent of the nation "believe that they are victims," is known to throw wild parties in the Hamptons, reports the New York Post.

The paper says "guests cavorted in a pool and performed sex acts, while scantily clad Russian women danced on platforms," at a rented home in Bridgehampton, N.Y., during a summer bash last year.

The Post said Leder went on something of a tear after his wife of 22 years, Lisa, cheated on him with her tennis instructor in 2009.

At the time of the Post's 2011 report about the divorced Leder's wild ways, the paper quoted a source who said: "So many girls think they're dating him. There are at least three that I know of."

Hip-hop/fashion mogul Russell Simmons; his ex-wife, Kimora Lee Simmons, and her new actor husband, Djimon Hounsou, have been guests at Leder's parties, but did not attend the Romney one.

Leder, who owns Sun Capital, a private-equity firm based in Boca Raton, Fla., went to the Wharton School. In 2011 he joined fellow Wharton grads Joshua Harris and David Blitzer to purchase the Sixers. Harris and Blitzer are co-managing owners with at least 10 other partners, including Will Smith, wife Jada Pinkett Smith and James Lassiter, Smith's longtime producing partner in Overbrook Entertainment, all of whom own much smaller stakes.

A Sixers spokesman said the team had no comment.

A woman who answered the phone at Sun Capital said there was nobody there who could discuss the Romney fundraiser, and a detailed email requesting comment was not answered Tuesday.

Steve Harvey speaks

Steve Harvey is serious about his retirement from comedy.

"I think this is really it for me. What else can I accomplish?" asked Harvey, who is now hosting a daytime talk show (2 p.m., NBC).

"Once you stop doing comedy, it's hard to go back. There's a certain muscle you have to have when it comes to doing standup," Harvey says.

He's exercising his talk muscle from Chicago where "the audience is more acclimated to daytime talk," having hosted Oprah Winfrey and Jerry Springer for so many years.

So how long does Harvey, who is trying to constantly evolve his career, want to stay hosting the show? "Eight years would be nice. Then I may look at it and do 10. I'll be 65 then," Harvey tells us.

Join us for Fringe's Fibber

Philadelphia Improv Theater presents four lineups of its popular Fibber show this week during the 2012 Philly Fringe Festival. Comedian/storyteller Hillary Rea hosts the shows, in which four people tell stories, one of which is fiction, and the audience has to decide which storyteller has made it all up.

The concept may sound familiar to fans of "The Howard Stern Show," who may know it as the Mike Walker Game. For years, National Enquirer columnist Mike Walker called in to Stern's radio show and told four celebrity stories, one of which was fake.

The Fibber shows take place at the Adrienne Theater (2030 Sansom) at 9 p.m. Thursday, Friday and Saturday and 5 p.m. Sunday.

On Friday night, Your Humble Narrator will be one of the storytellers along with "Project Runway" winner Jay McCarroll, Pizza Brain (2313 Frankford) co-owner Brian Dwyer, and Geekadelphia.com's Eric Smith. Tickets are $12 and can be purchased at livearts-fringe. ticketleap.com/fibber.
